Configuration Analysis of the Turbine–Fan High Pressure Water Separation Refrigeration System Based on the Energy Recovery Technology

The Turbine–fan air cycle refrigeration systems based on the reverse Bretton cycle have been widely used since the 1940s, whose cooling process is accomplished by an air cycle machine (a combined fan, and turbine machine), temperature and flow control valves, and heat exchangers using outside ambient air to dispense waste heat. It is characterized by fewer system accessories and the ability to refrigerate on the ground, but its refrigeration efficiency and dehumidification efficiency are low. So there are often free water in the cabin, which is an important factor that restricts the use of the system and the passenger comfort. The turbine–fan high pressure water separation refrigeration system based on energy recovery technology is proposed for the first time in this paper, which not only takes into account the characteristics of the traditional Turbine–fan air cycle refrigeration system, but also can use high pressure water separation technology to reduce the moisture content in the system, which fills in the blank of the development history of the air cycle refrigeration systems.
